This configuration helps to configure the sub-ring to run with or without an RAPS Virtual Channel. When this object is set to 'false', the sub-ring is configured to run with a R-APS Virtual Channel and both the traffic channel and the R-APS channel are blocked, when the ring port is set to blocked state. When this object is set to 'true',the sub-ring is configured to run without a R-APS Virtual Channel and the traffic channel is blocked but the R-APS channel is not blocked, when the ring port is set to blocked state [Reference : Section 10.1.14 of ITU-T G.8032 Y.1344 (03/2010)]. Administrator has to ensure that, this object is configured to true only in the nodes of a sub-ring. This object should be set to the same value (true/false) on all the nodes of the sub-ring. This object is applicable only when the compatible version is 2. This object can be changed, only when the rowstatus for this ring is not active.
